One of the new Xbox One exclusives revealed at the Xbox E3 media briefing was Scalebound from Platinum Games, revealed by none other than Hideki Kamiya himself. Not much is known about the game, and even Platinum Games isn't quite ready to reveal much more about the title.
So going from the reveal trailer, it's easy to surmise that the player character shares a world with some very unfriendly and monstrous wildlife. While you're armed with bow and sword like a certain Hylian from Hyrule, you'll also have a powerful dragon ally to back up. It seems you'll also have hidden powers of your own, but we'll just have to wait and see where Platinum will be going with all this.
To be sure, Kamiya himself promises "dragon fans around the world" that Scalebound will not disappoint. Scalebound will be the first title Platinum will be releasing in a new partnership with Microsoft.
